Definitions

  • the present invention is directed to a contact pin for insertion into contacting engagement with a through-opening in a printed circuit board.
  • a deformed elastic section of the pin affords the contact between the pin and the opening in the board.
  • Insertable elastic pins of the type mentioned above have the basic task of compensating for manufacturing tolerances in the diameter of the metallic surfaced through-openings in printed board circuit; they have been known for some time, for example, from DE-OS 26 56 736 in the form so that over a certain partial section of the post or pin length they have an approximately C-shaped cross-section, which, initially, permits a diameter variation or diameter adaptation to different hole diameters in the printed boards and secondly, by a snug fit in the board opening also affords the required contact pressure.
  • the object of the present invention to eliminate the above cited disadvantages of the pins known from DE-OS 26 56 736 and to provide a pin form which along with high diameter elasticity in the cross-section also results in good edge compression contact with printed board openings.
  • FIG. 1 shows the cross section, according to the invention, of the contact section of a wound post or pin with a shaping die
  • FIG. 2 is a partial view of a plug connector including the wound posts according to the invention.
  • FIG. 3 is a cross-sectional view of the deformed section of the post in a printed circuit board hole
  • FIG. 4 is a view similar to FIG. 3 with the post inserted into a smaller hole
  • FIG. 5 is a cross-sectional view of another embodiment of the deformed post.
  • FIG. 2 An axially extending elastic deformed section B (FIG. 2) of a wound post or pin 5 of a plug connector 6 according to the invention, is illustrated in transverse section in FIGS. 3 to 5.
  • the plug connector 6 is illustrated schematically in FIG. 2, and has the outstanding feature that the basic cross-sectional form is appoximately U-shaped, 3,4 or V-shaped 9,10.
  • the U-shaped section is made up of a bight portion or base 3 with legs 4 extending outwardly from the opposite base.
  • a transition portion E connects the opposite sides of the base 3 with the legs 4 and has a reduced thickness as compared with the legs.
  • the V-shaped section in FIG. 5 has a base 10 with legs 9 extending outwardly from the base.
  • the outside surface of the transition portion E is concave and is formed by an arc of a circle.
  • the outwardly directed edges R 1 , R 2 at the opposite ends of each of the free legs 4 form contact lines as shown with rounded surfaces, however, the contact lines need not be rounded.
  • the wall thickness of the base 3 or 10 is equal to or smaller than that of the transition portions E or E 1 .
  • the material of the base 3, 10 connecting and thereby stiffening the legs 4, 9 extends outside the center of gravity S.
  • the elastic deformed sections B according to the invention are to be manufactured in a die according to the schematic representation in FIG. 1.
  • the die is formed by a die bottom part 1 which fixes the pin width b in a cutout or recess of an equal width a, with formed-in bulges 1a forming the elastic transition portion E between the base 3 and the legs 4 and a correlated die top part 2, whose centered ram 2a serves essentially to form the profile or inside surface 3a, E', 4a of the deformed section B.
  • the lateral regions 2b of top part 2 serves to form the legs 4 with their outer contact edges R 2 .
